linux 安装 python3教程

linux 安装 python3

软件源

1. 下载软件

mkdir -p /soft 
cd /soft 
wget https://www.python.org/ftp/python/3.6.6/Python-3.6.6.tgz
yum install sqlite-devel

2. 安装

tar xf Python-3.6.6.tgz
cd Python-3.6.6
mkdir -p /usr/local/python3
./configure --prefix=/usr/local/python3
make && make install

3. 配置环境变量

ln -s /usr/local/python3/bin/python3 /usr/bin/python3
vim ~/.bash_profile
PATH=$PATH:$HOME/bin:/usr/local/python3/bin
source ~/.bash_profile

4. ssl相关

python在使用时，可能会使用ssl模块。所以在编译时，可以直接将ssl模块编译进去。

yum install openssl
yum install openssl-devel -y
cd Python-3.6.6
vi Modules/Setup #修改文件如下

    # Socket module helper for socket(2)
    _socket socketmodule.c

    # Socket module helper for SSL support; you must comment out the other
    # socket line above, and possibly edit the SSL variable:
    SSL=/usr/local/ssl
    _ssl _ssl.c \
        -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
        -L$(SSL)/lib -lssl -lcrypto

然后进行编译安装即可
